Gemstone clarity
Gemstone clarity is a quality of gemstone relating to the existence and visual appearance of internal characteristics of a diamond called "inclusions", and surface defects called "blemishes".
Inclusions may be crystals of a foreign material or another gemstone crystal, or structural imperfections such as tiny cracks that can appear whitish or cloudy. The number, size, color, relative location, orientation, and visibility of inclusions can all affect the relative clarity of a gemstone. A clarity grade is assigned based on the overall appearance of the stone under 10x magnification.
GIA specify gemstone in 3 Type. In each type, gemstones list is different. So gemstone's quality maybe same but the gem's inclusion maybe different. So you can check at the chart below.

VVS - Very, Very Slightly Included (the best) Minute inclusions that are difficult to see using 10X, and are not visible at all to the naked eye.
VS - Very Slightly Included Minor inclusions that are easier to see using 10X, but still not visible to the naked eye.
SI1 - Slightly Included I The inclusions are easily seen using 10X, and are noticeable with the naked eye.
SI2 - Slightly Included 2 The inclusions are more easily seen using 10X, and are quite visible with the naked eye.
I1 - Included 1 The inclusions are very obvious and they have a moderate negative effect on the over-all appearance or durability of the gemstone.
I2 - Included 2 The inclusions are very obvious and they have a severe negative effect on the over-all appearance or durability of the gemstone.
I3 - Included 3 The inclusions are very obvious and they have a severe negative effect on both the over-all appearance and durability of the gemstone.

For this grading, you will know some stone's kind in several type grading. So it is mean, different colors in same gemstone family is not same value amount.
